Copy Data with VNET gateway error
Hi TK12345
Thanks for reaching out to fabric community forum.
From the screenshot, we can confirm that the source-side connectivity appears to be working correctly because the preview data is loading successfully from the SQL source.
This helps narrow the issue down to the Lakehouse destination/write operation rather than the SQL extraction itself.
Could you please also share a screenshot of the Destination tab configuration from the same Copy Activity?
Additionally, could you help confirm the following:
- Which Lakehouse is selected as the destination, and how is the connection configured?
- Are there multiple pipelines or copy activities running in parallel and writing into the same Lakehouse/path simultaneously, especially creating Parquet files?
- Are you writing into the Tables section or the Files section of the Lakehouse?
These details will help determine whether the issue is related to destination configuration, concurrent write operations or backend behavior.
Hi,
Thanks for your reply. For the destination I will share the screenshot. FYI, I've tested with a new lakehouse, our normal lakehouse connection, delta, parquet, new schema, dbo, files parquet. Besides that, it is also just a duplicate of another pipeline that is just working fine with the exact same logic. There are no multiple pipelines running, just 1, with 1 table.
Preferably I would write this data into tables. But checked all the options, all with same error message.
